Common pitfalls when preparing a Business Letter to Auditors
- Omitting attachments or schedules referenced in the letter, which forces auditors to re-open requests and delays finalization.
- Using vague language for material items rather than precise dollar amounts and dates, which creates ambiguity for audit evidence.
- Failing to obtain appropriate internal approvals before signing, risking retractions or qualified auditor responses.
- Delivering unsigned or incorrectly dated letters, which invalidates the representation and necessitates re-execution.

FAQs and troubleshooting for Business Letters to Auditors
-
Can this letter be e-signed?
Yes. Electronic signatures are enforceable under the ESIGN Act (15 U.S.C. ch. 96) and UETA where adopted, provided intent, consent, attribution, and record retention requirements are met.
-
When is notarization required?
Notarization is usually unnecessary for routine audit representation letters. If the auditor requests a sworn affidavit, obtain a notary or check state notary/RON rules first.
-
Who must sign the letter?
An authorized officer with management responsibility for the representations should sign. Authority should be consistent with corporate governance and filings.
-
What supporting documents should be attached?
Attach schedules, reconciliations, contracts, and any documents referenced in the letter. Label attachments clearly and reference them in the body.
-
Is an e-signed PDF admissible?
Yes. PDFs with a verifiable audit trail and metadata showing signer identity and timestamps satisfy evidentiary needs under ESIGN and most state laws.
-
How to correct an error after signing?
Issue a corrected letter signed by the same authorized signer and clearly mark it 'Corrected' with an explanation and date; retain both versions for the audit record.
